PRESS TIMER.

Application inea may 17, 1924. lserial No. 714,130.

This invention relates to presses and more particularly to improvementstherein designed to control the duration of pressure imposed by apressing machine; and While l have chosen a conventional type garmentpresser with which to disclose the principle of my invention, it is tobe understood how my press timer improvements may be used on other typesof pressing and work treating machines.

Purpose.

Broadly speaking an object of my invention is to increase the eiliciencyof pressing maclnnes, as for example hot jiaw machinesy used in pressingand ironing the Work; andv the adoption of this invention renders itpractical to increase the working temperature ot' the pressing memberswhereby the work is more quickly dried and ironed; and such increasedhigh temperature pressing jaws are not permitted to injure the work asby o'ver heating for the reason that the timer mechanism constitutingthis invention cuts short the pressure and contact period by causingthepress to automatically open at a time predetermined as most eicient forwork of a given character. Since this improved machine is capableoffsafely applying greaterheat to the garment, it follows that the workis pressed more rapidly and the. production of the machine is increased.

In somefcases it may be undesirable to raise the temperature of thepressing members and in such event this press timer has its mostimportant uses in that the human element and guess work a-re removedbecause an operator using present day inachinesmay himself open thepress too soon one time and leave it closed longerA than reallynecessarv the next time thereby not working his machine to the bestadvantage'and what is more failing to produce uniform work. In thisconnection the timer is set to open at exactly the desired elapsedpressing period so no time is lost in over pressing and the quality ofthe work is not lowered due to under pressing.

In addition to the above it may be said that. another object is toproduce press timer control means `highly adapted to garment pressesandlaundry ironers; and further-l more my improved machine incorporatesthe timer element as va. unitary structure therewi th and not as aseparate unit. Besides this in'iprovement and distinction, my presstimer is itself driven by the press operating mechanism, as by anelectric motor used to produce final pressure, and so separate drivingmeans is not necessary for the press driving means is used to drive mypower timed tripping mechanism.

i Synopsis of the invention.

upon the particular type of mac ine at.

hand. In the present instance I have chosen a power press of the motordriven type adapted to be closed by hand and the final y pressureimposed by motor, and a continuously running motor is employed whichconveniently provides a driving means for the timer and automatic pressopening device constituting the principal feature of this invention.

A synopsis of the invention will be given and reference is made toFigure 5 for the purpose of explaining how the continuously runningmotor means is employed to slowly drive a graduated trip member employedto operate a clutch, a switch, or any other suitable appliance by whichthe press is caused to automatically open. A main drive shaft 10 iscontinuously driven by the motor means and carries a worm pinion 11meshing with a worin wheel 12 which is fixed to and drives a spur gear13 meshing with a large gear 14. The result of -this gear train, of one,two, three or more reductions, is to very slowly drive the final spurgear 65. A gear rack 16 meshes with the last driven gear 65 and travelsvertically or horizontally, as the case may be. The gear rack isprovided with a ratchet bar 17 carrying a slider 18 which travels withthis trip member 16-17. Slider 18 is provided with a spring pressedreleasable dog 19 whereby it is adjustably fixed to the ratchet teeth ofthe bar and since the bar 17 is graduated, this slider may be set inpredetermined indicated position von the trip member and caused toimpinge a lever arm 2U to oscillate the shaft 21 at the lapse of a shortor long period of time depending whether the slider 18 is set toward thefront end as at 15 or the rear end as at 60 on the graduated bar. Forexample should the trip member or slider 18 be set near the top of thebar as at 15, it will reach engagement with the control lever 20 muchearlier and thereby cause a much shorter pressing duration than when thetrip member' is placed for example at the lower end of the bar. It is tobe understood that the shaft 21 is subjected to partial rotation whenthe trip member 18 is forcibly driven thereagainst to cause the pressopening mechanism, described elsewhere, to function; and the arm 2O maybe employed to open an electric switch to stop a motor, or actuate aclutch to disconnect rotating parts.

Having given in brief a plan of the invention, a typical pressingmachine will now be described; thereafter an explanation will be givenas to how the press timing and automatic opening device is combined withthe press to take the opening function of the pressing machineout of thehands of the operator to improve the character of the work and speed theoutput.

A typical garment prees.

A press frame 24 supports a press buck 25 and a head 26 raises andlowers in relation to the buck to produce pressure on the work betweenthe pressing members or jaws.

A press lever or oke 27 is pivotally mounted at 28 on the rame 24. Therear end of the press lever is provided with a swing link 29 which ispivotally connected to the lever as at 30. The lower end of the link 29is provided with pin 31 disposed in the bottom end of a slot 32 made inthe upper extremity of a support link 33 which is itself pivotallyconnected at 34 to a power lever 39 fulcrume'd on the frame as at 37.

An overbalancing arm or swing link 35 has its upper end pivotallyconnected at 3G with the link 29 and its lower end pivoted in the frameat 37. against, so to speak, the connected links 29 and 33 and the heavyweight of the link 35 imposes an overbalancing factor against thestraightened links 29 and 33 to such an extent that said links 29 and 33are caused to move outwardly when the operator removes his hand from apress closing handle 38 provided for manually closing the press. Theslot- 32 permits the weight of the link 35 to move the pin 31 outwardlyto the top of the slot 32 by the time the link 33 has folded down into ahorizontal position to cause the press head 26 to open high above thebuck under the infiuence of a counterbalance weight 48. lVhen the -frontend of the power lever is thrust downwardly by power means to behereinafter described the straightened links 29 and 33 thrust upwardlyunder great force and thus impose high compression between the pressingjaws 25 and 26.

Any suitable motor means for forcibly operating the power lever 39 maybe einployed and in the present instance there is shown an electricmotor 41 driving through a fiy wheel 42 and continuously rotating a maindrive shaft 10, which has a .worm wheel 43 fixed on the shaft andmeshing with a worm wheel 44 carried in a gear housing 45. The motorcontinuously drives the worm wheel 44 which is freely journaled on a camshaft 4G on the outer end of which is anchored a cam 47 .engaging theaforesaid power lever 39. The power lever 39 has an up and down throwiequivalent to the throw of the cam and the cam is driven downwardly andstops to hold the press under high compression and thereafter rotates18() degrees to its uppermost position tofpermit the rear end of thelever 39 to drop downwardly with its pin 34 loosening up and removingcompression from the pressing members to such an extent that the link 35overbalances the straightened condition of the links 29 and 33 therebycausing them to move outwardly to permit the head 2G to lift high abovethe buck. Any suitable form of periodic driving means may be employed torotate the cam 47 to its two extreme positions, up and down, and stopthe cam at each point for it is understood how a pressing The link 35leanslever 39 up.-

In some instances a stop and start motor may be employed whereupon aswitch is necessary for making and breaking the circuit supplyingcurrent to the motor, and my invention contemplates the use of either acontinuously running motor or a stop and start motor. In the presentapplication I have illustrateda` continuously running motor as aforesaidand therefore have incorporated a stop and start clutch of any approveddesign whereby the motor is perl mitted to run continuously and theclutch is caused to automatically start and stop the cam 47 when thepress is to be opened and closed under high pressure. I have illustratedin Figure 1 one suitable formA of clutch mechanism 4interposed betweenthe periodically driven cam shaft 46 and continuously driven motorshaft\10 but it is understood how any other character of clutch may beused. The clutch illustrated may comprise a disc 49 slidably lixed onthe cam shaft 46 anda hub 50 normally lies in contact with an arm51-iXed on a shaft 52. A clutch control lever 53 is fixed to thesl1aft`52vand so arranged that the arm 51 is moved towards the hub 50 toengage the clutch when the lever 53 is swung outwardly.

The disc -49 carries-driving pins 54 which engages the continuouslyrunning wheel 44 to piek up the disc 49 and cam shaft 46 to causerotation of the cam 47; and a spring and trip mechanism 55 acts to throwthe disc 49 with the pins 54 outwardly thereby disengaging the clutchdisc 49 from the continuously running worm wheel 44 to permit the camshaft 46 and cam 47 to stop after they have been driven one-halfrevolution.

A manualcontrol means is provided at the front of the pressing machinefor controlling the action of the lever 53 to impose the final pressureunder the control of the operator, and such means consists of a handle56 carried on a shaft 57 and a shaft is provided with a pendulum bob 58which acts to hold the handle 56 inl its normally upwardly limitedposition 'and therefore after the operatori has thrust thehandle-downwardly, it automatically returns to the position shown inFigure 1 due to the weight of the bobmember 58. The member 58 coopcrateswith the clutch lever 53 to cause engagement of the clutch to produce ahalf revolution of the cam 47 and to this end adog 59 is pivoted in thebob and forcibly thrust against the upper end of the clutch lever 53when the bob 58 swings outwardly under the influence of the manualdownward movement of the handle 56, but the dog 59 pivots upwardly andswings past the clutch lever 53 on the back return movement of the bob58 and again cornes to rest in the position shown in Figure 1 ready toactuate the clutch lever when the clutch is to be engaged for imposingor removing high pressure. The foregoing description covers in general amotor driven high press-ure pressing machine of one suitable type withwhich to combine my invention. A description will now be given ofprinciples of timer mechanism employed to automatically operatethehandle 56 and shaft 57 for engagement of the clutch to rotate the cam 47to upward position to automatically open the press. By employing myinvention, the operator engages the clutch for the purpose only ofimposing pressure and thereafter the press timer operates the shaft 57to engage the clutch to cause the cam 47 to move upwardly to remove highpressure. Therefore the operator and press timer take time about, so tospeak, in engaging the clutch.

The prese time?" mechanism.

i The timer mechanism supplies a means for automatically engaging theclutch mechanism at. a predetermined time whereby the press is-caused toautomatically open and the mechanism necessarily requires driving meanswhich is supplied from the main drive shaft 10 as-aforesaid, and to thisend the worm 11 is fixed on the main drive shaft 10 and continuouslydrives a gear 12, or train embodying several stages of gear reductions,for the purpose of producing a substantially slow motion at the end ofthe train as here inbefore described in the synopsis of the inventionbut for the purpose of illustrating the principles involved withoutcomplicating the disclosure with unnecessary parts,

as uby duplication of gears, I have diagrammatically illustrated theprincipal features of the timer in Figure 4 where one gear 12 takes theplace of a multi-stage gear train reduction seen in Figure 5; and thisgear 12 for all practical purposes is sufficient for an understanding ofthe invention; However, reference is made to Figure 5 for illustratingthe engineering principles involved, for those skilled in the art willappreciate that a single gear reduction as shown in Figure 4 is notsuiicient for producing the required slow motion trip action.

A commercial machine manufactured in accordance with the principles ofmy invention requires a multi-stage gear reduction set by which thehighspeed rotary means is resolved to a very substantially slow speedmotion, and these parts are all incorporated Within a comparativelysmall size gear housing but the housing is dispensed with in describingmy invention in order to expose the parts for examination. i

llO

The continuously running power shaft 10 continuously drives the gear 12,or gear train 12-14,` to very slowly rotate a shaft 61. One end of theshaft 61 is shown as being splined as at 62 and a clutch member 63 isconfined on the splined end to slide back and forth and engage a clutchpart 64 which is made integral with a spur gear 65 freely journaled onthe shaft 61 and not subject to being driven by the said shaft 61-62until suchtime as the said clutch 63-64 is thrown into engagement bymeans'hereinafter described. The spur gear 65 remains stationary duringthe continuous' rotation of the gear 12, shaft 61, and clutch member 63during the time the head 26 and front endof the power lever 39 is upunder the influence of the spring 40.

Automatic means are provided for shifting the clutchmember 63 backv andforth on the splined end 62 of the continuously runningv shaft 61' forstopping and starting the spur gearv 65, for it is this small slow speedspur gear 65 which is employed to drive a graduated trip member employedto automatically open the press at the end of the fixed andpredetermined pressing period.

A clutch fork 67 is made a part of a lever 68 which is pivoted at 69 tosome suitable part of the pressing machinevframe 24; and the rear end ofthis lever 68 may be made with a slot 70 in which the upper end 71 of atimer control lever 72 is designed to slide back and forth to pivot thelever 68 about its fulcrum point 69 to4 engage the clutch 63-64 anddisengage it automatically under the control of the combined motor meansand timer mechanism. The lower end of the lever 72 is provided with aslot 7 3 which is confined on a pin 74 anchored to the lower leveralready described. The lever 72 is fulcrumed as at 75 upon some suitablefixed part or bracket of the machine frame 24.

It is to be noted how an up and down mo` tion of the power lever 39swings the timer control lever 72 about its fulcrum point 75 forsimilarly swinging the clutch fork 67 in and out to engage the twoclutch member 63 and 64. When the power lever 39 goes down under theinfluencent the cam 47, the clutch 63-64 is engaged thereby causing the'spur gear 65 to start rotation and it continueslto be driven in fixedengagei'nent with the gear 12, or gear train 12-14, until an upwardtravel of the cam 47 permits the power lever 39 to rise whereupon thetwo levers 72 and 68 undergo a reverse movement to that alreadydescribed thereby disengaging the clutch 63,64, causing the said spurgear 65 to cease revolving.

The gear ruck, or other suitable slow movement part, is held inengagement with the periodically driven spur gear 65 by any suitableguide means designed to confine a gear rack in operative position aswill be understood by those conversant with the art, but such guide isomitted from the present disclosure to clarify the illustrations anddescription. The timed tripping bar 16, when mounted in horizontalposition, as in Figure 4, is provided with a spring 76 or other suitablemeans for returning it to its normally inactive position after it hasperformed the function of engaging the clutch to initiate the pressopening movement. However, when the timed trip bar is mounted in avertical plane, as in Figure 5, it returns to its lowermost normallyinactive position by its own Weight.

A control lever 20 is -pivoted on the frame 24 and has an arm 77projecting through a slot 78 made in a control arm 79 anchored to themotor clutch control shaft 57 already described. Motion of the arm 20oscillates the shaft 57.

Uomplete operation.

It is now understood how a mechanically operated arm 79 is anchored tothe motor clutch control shaft 57 to oscillate that shaft by power meansfor the purpose of working the clutch lever 53. The shaft 57 isoscillated one time by the operator to produce final pressure and thenext time by the machine to release final pressure.

The work is spread upon the press buck and the operator pulls the head26 down by the handle 38 which causes the links 29 and 33 to straightenup into the position shown in Figure 2. The operator holds the head 26down by one hand and quickly thrusts the main control handle 56 downwith the other hand which engages the motor clutch 44--49 therebycausing the cam 47 to move downwardly with great force upon the lever 39to impose high compression between the press ]aws. Y

.When the power lever 39 goes down, the pin 74 carried thereby swingsthe lever 72 which in turn swings the clutch fork lever 67 to engage thetimer clutch 63- 64 which picks up the spur gear 65 and sets the timerin operation by imparting movement to the gear rack 16 driving itsadjustable slider member 18 straight ahead toward the press opening triplever arm 20; and it is noted that the. motor 41 continues to run whilethe press stands still under pressure. When the trip slide 18 reachesand impinges thel arm 2() there follows an oscillatin motion of theshaft 57 to again engage t e power clutch 44-49 which causes a 180degree upward movement of the cam 47 permitting the power lever 89 totravel upwardly under the tension of the spring 4() which again swingsthe timer control lever 72 to disengage the clutch 63u64 therebydisconnecting the spur gear 65 from the gear 12, or from the gear train12-14. the result of which is to permit the spring 76 to quickly return20vjustalole means on the graduated member to ing means a connectionestablished bet-Ween the mechanism and the press opening means wherebythe press opening means is set in operation when the press goes underhigh compression, a graduated member driven by the motor means after thepress closes, ad-
